distribution plan (a “Plan”) and employ a managed distribution and/or an
option over-write policy to support a level distribution of income,
capital gains and/or return of capital. The fixed amounts distributed

shareholders in order to maintain a level distribution.

1The Plan Fund estimates that it has distributed more than
its income and net-realized capital gains in the current fiscal year;
therefore, a portion of your distribution may be a return of capital. A
return of capital may occur, for example, when some or all of the
shareholder’s investment is paid back to the shareholder. A return of
capital distribution does not necessarily reflect the Plan Fund's
investment performance and should not be confused with ‘yield’ or
‘income’. When distributions exceed total return performance, the
difference will reduce the Plan Fund’s net asset value per share.

The amounts and sources of distributions reported are only estimates
and are not provided for tax reporting purposes. The actual amounts and
sources of the amounts for tax reporting purposes will depend upon each
PlanFund’s investment experience during the remainder of its
fiscal year and may be subject to changes based on tax regulations. Each
Plan Fund will send you a Form 1099-DIV for the calendar year that will
tell you how to report these distributions for federal income tax
purposes.

*Portfolio launched within the past 5 years; the performance and
distribution rate information presented for this Fund reflects data from
inception to 3/31/2018 .

Shareholders should not draw any conclusions about a Plan Fund’s
investment performance from the amount of the Plan Fund’s current
distributions or from the terms of a Plan Fund’s Plan.
